Hawthorn (Crataegus oxycantha) has been clinically established to help scavenge free radicals. It has also been observed to improve the functioning of the heart by aiding the flow of blood to the cardiac muscles. Hawthorn creates a consistent, controlled effect on the heart and circulatory system, which helps to sustain cardiac health. Many experiments have revealed Hawthorn's capability to reinforce healthy cardiac muscle performance, cardiac blood distribution, and exercise endurance.*
